transmission temp

[craig long]

i have a set of guages now and the trans temp usually rests at 140, which is bottomed out on my guage, but will rise under pulls and plowing. what is an average low temp under no load, an average temp under load and what would be the max allowable temp? thank you?

What is the outside temp? How much are you pulling? My truck runs about 100-105* empty running during stop and go traffic. At any time, 195+ is danger zone.

outside temp has been freezing lately, in kansas city. i may have a loose wire. sometimes the guage dances, then reads nothing, then reads 180-200 while pulling a twin axle landscaping trailer. where is this guage plugged into so i can check the wiring? thank you

Usually its around 60-80 degrees above ambient outside temps without a load. And yes when you get around the 200 degree mark its time to pay attention and pull over if it gets hotter

The sensor is on the driver's side of your tranny. You should be able to spot it once you get down there and look for it. It should have one wire coming off it.

what year is your truck?

[craig long]

[craig long]

My guess is so he knows which exact tranny you have. I would imagine some deal with heat better/differently than others.

Because that sounds a bit high for a 5r110 trans. I suggest getting a 30K+ rated trans cooler and add it to your truck.

EDIT: You have a 4r100.
